Since the construction takes time and effort, there is a problem that the construction period is easily delayed and the construction cost is easily increased.
In particular, when the roof has a slope, further consideration is required for the safety of the work, so that the work efficiency is reduced and the construction cost is further increased.

る。FIG. 1 is an explanatory diagram for explaining an example of an embodiment of the present invention. Referring to FIG. 1, at a construction site of a building in which roof construction is being performed for construction of a steel roof and installation of a girder has been completed, installation of a plurality of purlins 1 has been completed. The following describes a process of suspending and lifting a girder material, and disposing and fixing the girder material at a predetermined position.

材1の配設間隔と同じになっている。First, the set jig 2 is placed on the ground G.
The set jig 2 includes a frame main body 26 in which four rectangular steel pipes 21 to 24 are assembled in a cross-girder shape and reinforced by four reinforcing members 25 as shown in the drawing, and among the four rectangular steel pipes 21 to 24, A total of 18 positioning metal fittings 27 for positioning the purlins 1 in a state where they are arranged at predetermined intervals are fixed to the pair of opposed square steel pipes 21 and 23 as shown in the figure, for a total of 18 positioning metal fittings 27. I have. In the illustrated example, the positioning metal fittings 27 have a U-shape that can receive the purlin 1, and the arrangement intervals of the positioning metal fittings 27 are different from those of the purlin material 1 on the girder (not shown). It is the same as the arrangement interval.

である。Since the set jig 2 is constructed as described above, the purlin 1 can be extremely easily spaced at a predetermined interval only by setting the purlin 1 in the positioning fixture 27 of the set jig 2. 9 lines can be arranged. It is needless to say that the number of the purlins 1 that can be set by the setting jig 2 is not limited to nine, but can be appropriately determined.

長さに保持することができる。After arranging nine purlins 1 on the set jig 2 as described above, each purlin 1 is connected by a plurality of full screw bolts 28. In this way, the interval between the purlins 1 can be maintained at a required length until the nine purlins 1 are suspended and fixed on the girder of the roof of the building and in the subsequent processes. it can.

Done using The hanging jig 3 is configured by assembling four H steels 31 to 34 in a cross-girder shape. Four H steels 31-34
The lower surface 3 of each of a pair of opposed H steels 31 and 33
Nine L-shaped locking plates 35 are fixed to 1A and 33A at the same arrangement interval as that of the positioning fitting 27. An opening for passing a shackle or the like is provided on the upper surface 31B, 33B of each of the pair of opposed H steels 31, 33 so that the lifting jig 3 can be lifted by a lifting device such as a crane. Pair of lifting plates 36, 3

揚げることができる。Since the suspending jig 3 is configured as described above, the suspending jig 3 is suspended on the nine purlins 1 set on the set jig 2 as described above. Hanging jig 3
The main purlins 1 corresponding to the locking plates 35 are slid so as to slide in from the respective side surfaces, and in this state, the nine purlins 1 integrated with each other can be lifted by the hanging jig 3. .

ら外れ落ちにくい姿勢を取るようにしてもよい。Here, when the nine purlins 1 locked as described above on the locking plate 35 of the hanging jig 3 are lifted and lifted off, they fall off the locking plate 35 due to a crosswind or the like. In order to prevent such a situation, the locked state between the purlin 1 and the locking plate 35 of the hanging jig 3 can be firmly held during the lifting operation by appropriate means using a rubber band. It is preferred that In addition to or instead of this, during the lifting operation by the hanging jig 3, the hanging jig 3 is inclined so that the H steel 34 is higher than the H steel 32, thereby locking the purlin 1 You may make it take the attitude | position which is hard to fall off from the plate 35.

示されている。FIG. 2 shows an example in which when the purlin 1 is lifted by the hanging jig 3, the rubber belt 38 is used to strengthen the locking between the purlin 1 and the hanging jig 3 so that the purlin 1 is hard to be detached. It is shown.

を完了させることができる。After the purlin 1 is lifted and arrived at the roof by the suspending jig 3, the purlin 1 is lowered together with the suspending jig 3 onto a girder (not shown). Anti-slip members for stably installing the purlin material 1 at predetermined positions are attached to the girder materials at predetermined intervals, but are suspended by the hanging jigs 3 as described above. The interval between the purlins 1 is equal to the arrangement interval of the anti-skid members. For this reason, if the purlin 1 is lowered to the required position of the girder material and the connection with the hanging jig 3 is released, the required arrangement of the nine purlins 1 is received in a state where the nine purlins 1 are respectively received by the corresponding anti-fall members. Can be completed.

できる。That is, even after the nine purlins 1 are set so as to lean against the anti-slip, the rubber band 38 is removed, and the hanging jig 3 is removed, the nine purlins 1 are still displaced. Because it keeps the state where it is arranged at the required interval at the predetermined position without falling etc.
The attachment of the purlin 1 can be completed only by fixing the purlin 1 to a predetermined position of the girder by a method such as bolting.

でき、作業効率を上昇させることができる。Since the set jig 2 and the suspending jig 3 can be used any number of times, the set jig 2 and the suspending jig 3 are used to construct a sloped or non-graded roof. If the purlin material 1 is hoisted and lifted by repeating the above operation, a plurality of purlin materials can be used without performing the inefficient work of manually placing the purlin material 1 at a predetermined position one by one. One can be placed in place at a time.
Since the work on the girder material is performed only by bolting the purlin 1, the work is not required, so that the work efficiency is improved, and the work period is not delayed. In addition, when the roof has a slope, work on sloped girder materials is reduced, which increases work safety and allows workers to concentrate on work, increasing work efficiency. Can be done.

なくなり工事コストを削減することができる。According to the present invention, the purlins are lifted and lifted while holding a state where the purlins are arranged at required intervals on the ground by using a jig.
The work of arranging one book at a predetermined position is eliminated, and only the bolting is required. Therefore, the safety of the work is increased at the same time as the work is not required, and the work can be concentrated on the work. Therefore, the work efficiency is increased, and there is no possibility of delaying the construction period, and the construction cost can be reduced.
